*** A. Modelled scenarios ***
We report simulation results for 5 scenarios: a baseline scenario of no scale-up, and four different packages of scale-up in which we improved the availability of imaging or treatment modalities and 
quality of care to the mean level of high-income countries. Scenario names are used as prefixes for each results file.
